Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 520768, here are decompositions:

5 + 520763 = 520768
47 + 520721 = 520768
89 + 520679 = 520768
137 + 520631 = 520768
179 + 520589 = 520768
197 + 520571 = 520768
239 + 520529 = 520768
317 + 520451 = 520768

Showing the first eight; more decompositions exist.
